(new Question)

Motivation

The emerging of NGN applications (IMS, IPTV services, broadband TV, fixed mobile convergence) in the fields of telecommunications impacts the domain of tests and instrumentations. Requirements for reactivity, interoperability and scalability in terms of performance measurement are of another order of magnitude than at the time being. ITU-T standardized test and instrumentations techniques for a lot of transport techniques. Therefore the pressure impacts more the reactivity, the interoperability and the scalability of the interfacing of tests and measures with higher NGN constituent parts:

• NGN transport relies on heterogeneous transport techniques. The test and measure technique and instrumentation for NGN requires a common framework to harmonize functions and methods and to avoid duplication of works already available in other SDOs.
• The maintenance of frame-based multi-operators transport requires tests and measurement of the performance of the whole transport and of the performance of each network crossed. Tests, measurement and results collection must be adapted to multi-operator transport context.
• NGN functionalities such as terminals mobility, fixed-mobile convergence are already deployed. Tests, measurement and results collection must be adapted to terminal mobility.
• IPTV services connect millions of terminals. Tests, measurement and results collection must be adapted to collect and organize massive simultaneous measures.
• Measurement and results collection require a ground truth operational interoperability to gain reactivity and scalability.

Question

Study items to be considered include, but are not limited to:

• What test, measurement and collection techniques for use on NGN frame-based telecommunications systems and their constituent parts, and what should be the specifications?
• What measurement and collection techniques to assess the performance of NGN transmission involving terminal mobility need to be specified by ITU-T, and what should be the specifications?
• What measurement and collection techniques to assess individual network impact on the performance of a multi-operator transport need to be specified by ITU-T, and what should be the specifications?
• What measurement and collection techniques to assess the performance of massive simultaneous transport contexts need to be specified by ITU-T, and what should be the specifications?

Tasks

Tasks include, but are not limited to:

• Specify a framework for NGN test and measure technique and instrumentation for use on NGN telecommunications systems and their constituent parts which is consistent with terminal mobility, massive simultaneous measures and multi-operators transport;
• Specify the functions that allow results collection of measurement involving terminal mobility situation, massive simultaneous measures situation and multi-operators transport situation;
• Specify the transport control functions and management functions that allow a test instrument to interact with NGN service control and to gain access to a transport layer network;
